onChange event not fired

[spajdo]

Hi. This plugin is not working for me.
What I did wrong?
My code is:

@override
void initState() {
  super.initState();

  KeyboardVisibilityNotification().addNewListener(
    onChange: (bool visible) {
      print(visible);
    },
  );
}

And flutter doctor -v:

I am also having this issue. But it is only reproducible on Emulator. On real device everything is working fine.

Ok, I tried previous versions and I had to stick with 0.5.2. The other versions:

# 0.5.6 doesn't work
# 0.5.5 crashes
# 0.5.4 crashes
# 0.5.3 doesn't work
